BOLTlNG-REEL.

SPECIFICATION forming part of Letters Patent No. 406,384, dated July 2, 1889.

Application filed July 12, 1888. Serial No. 279,769. (No model.)

Figure l is a central vertical section through my improved bolting-reel and casing. Fig. 2 is a cross-sectional View of the same on line a: 00, Fig. 1. Fig. 3 is a detail cross-sectional view of the reel in the plane indicated by line z .2, Fig. 1. Fig. at is a rear end View of the reel. Fig. 5 is a detail view of a bucket detached. Fig. 6 is an end view of the machine.

This invention is an improvement in bolting-reels, and its objects are to relieve the cloth of a great part of the weight of material passing through the reel, to agitate this material and provide means for elevating the same, carrying it from the bottom of the reel up and around and dropping it against the descending side of the cloth and to provide knocking or cloth-jarring devices which will serve to clean the bolting-cloth of the reel.

The invention consists in the novel devices and construction of parts effecting the abovementioned objects, and also in certain other novel details of construction and combination which are hereinafter described and claimed.

Referring by letter to the accompanying drawings, A represents the casing of the reel, and D is the reel mounted therein on a shaft (1, which has bearings in cross-bars B B at the ends of the casing. At the opposite ends of the reel are mounted two spider-frames F F, which are constructed alike, but stand in opposite directions. Each of said frames has a hub portion F and a deep and narrow rim portion f, mounted on the hub by connecting-arms f, as shown. From the inner faces of rims f project a series of concentric'studs G G, and about midway between each pair of studs, but nearer the periphery of the rim, is an opening g. The openings correspond in number to the studs, and the two spiderframes are so adjusted that the studs and openings of each are exactly opposite each other. These are hereinafter referred to.

The reel-head H is attached to one spider F by screws or otherwise, and is supported thereon. The head is of greater diameter than the spider, and has a central annular opening which is closed by a plate or ring 0 on the end of a feed-delivery spout c, which is connected to the hopper (L, as shown. The edges of plate 0 areship-lapped with the edge of head H, making a close joint therewith. The plate is stationary with the spout, but the lapped joints prevent leakage of material between the plate and head H.

At the center of the reel is a spider I, having a thin rim '1', which assists in supporting the bolting-cloth.

J is the tail spider of the reel, which is of larger diameter than spiders F, and has a thin rim j, supported on arms radiating from a proper hub on shaft D, as shown. The bolting cloth or screen K, of proper material, is stretched between head II and spider J, being secured to the rim of the latter, so that the material can pass between the periphery of spider F and rim j. The cloth is stretched over spider I, as shown. Before the reel is covered, however, I mount a series of elevatorbuckets L between and upon spiders F F. The buckets are preferably made of sheet metal, and of a length equal to the distance between the inner faces of the rims of spiders F F. They have an angular inwardly-standing portion L, and at the opposite edge an outwardly-curved portion Z, which latter portion forms the bucket proper.

M M are short studs secured to or formed on buckets L, at the opposite ends thereof and 0 at the angle formed by part L. These studs are loosely pivoted in the corresponding openings g g of the opposite spiders F F, and thus suspend the buckets thereon, so that they can swing freely. The buckets are of such size that when they are all in position the part Z of one bucket lies close to the part L of the adjoining bucket. The angle portions L of the buckets (when the latter are at the bottom of the reel) direct the material against the cloth and into the buckets. Vithout these angles a large portion of the material would ride over the buckets and thus pass through the reel on the inside of the buckets unbolted. The studs G prevent the buckets swinging too far inward, and the rim '1 of spider I prevents their swinging too far outward and striking the cloth. However, to insure their not striking the cloth if the latter should sag, I employ blocks on m, which are secured to the portion Z of the buckets directly within rim 2 and which blocks project beyond the edge of the bucket, so that they will strike the rim. These buckets, while the reel is revolving, scoop up the accumulated material in the bottom of the reel, relieving the cloth of its weight, and carry it up with them until they begin to descend at the upper and opposite side of the reel. Here the material is discharged against the cloth on the descending side of the reel, as evident. -lVhile ascending the buckets rest upon lugs G G, and are partly supported thereby, but when descending they swing outward and fall against rim 2', the blocks m striking said rim and jarring the same and the cloth, and as each bucket strikes the rim in succession, the series of blows keeps the bolting-cloth clean. The buckets swing by gravity as the reel revolves, moving automatically, and pick up and distribute the greater part of the material, causing the reel to bolt on both sides, and the tendency of the material to collect at the center and lower part of the reel is also obviated by the buckets.

Having described my invention, I claim 1. A bolting-reel covered exterior-1y with suitable material, in combination with internal elevator-buckets pivoted in end frames of the reel, said buckets being limited in their outward movements by striking and jarring the. frame of the reel, and in their inward movements by studs on the end frame, substantially as specified.

2. A bolting-reel having its outer surface covered with bolting-cloth, in combination with a series of swinging elevator-buckets therein moving automatically by gravity as the reel revolves and having blocks which strike the reel-frame when the buckets swing outwardly while at the descending side of the reel, whereby the buckets answer the double purpose of elevators and cloth-cleaners, and the stops for limiting the inward swing of the buckets, substantially as specified.

3. -In a reel, the combination of the central shaft and the opposite spider-frames thereon, provided with inwardly-standing studs, with a series of elevator-buckets having an angular portion I. and an ontwardly-curved portion I, and studs M M on the ends of said buckets journaled in the opposite spiderframes, substantially as set forth.

at. In a reel, the combination of the opposite spider-frames F F, having stop-lugs on their inner faces, and the longitudinal swinging elevator-buckets L L mounted thereon, with the reel-head and the tail-spiderof larger diameter than and supported 011 said spiderframes, and the boltingeloth attached thereto, substantially as and for the purpose set forth.

5. The combination of the central shaft, the opposite spider-frames mounted thereon, having lugs on their inner faces, with the series of longitudinal swinging elevator buckets mounted on said frames, the reel-head II, the spiders I and J, and the bolting-cloth, all substantially as described.

0. In a bolting-reel, the combination of the central shaft, the spider frames mounted thereon at opposite ends of the reel and having inwardly-standing lugs, and a series of swinging longitudinal elevator-buckets mounted between said spiders and limited in their inward movement by said lugs, with the reel-head, tail-spider, and intermediate spider, of larger diameter than said frames, and the b0lting-cloth stretched thereon and inc-losing said spider-frames and buckets, the buckets being provided with blocks which strike the rim of the central spider when at the descending side of the reel and jar the same, all substantially as set forth.

In testimony that I claim the foregoing as my own I afiix my signature in presence of two witnesses.

CHARLES A. BARNARD.
